Oops, I forgot to mention that Arabic numerals are written as:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9 = ٠, ١, ٢, ٣, ٤, ٥, ٦, ٧, ٨, ٩
Thus, 10,11,12, and so on = ١٠, ١١, ١٢, and so on
Number 20 to 29
Number 20 is called عِشْرُون 'ishruun. For numbers 21 to 29, just add َو (and) in between the number and عِشْرُون as follows:
عِشْرُون - ٢٠
وَاحِدْ وَ عِشْرُون - ٢١
أِثْنَانِ وَ عِشْرُون - ٢٢
ثَلَاثَ وَ عِشْرُون - ٢٣
عَرْبَعَة وَ عِشْرُون - ٢٤
خَمْسَة وَ عِشْرُون - ٢٥
سِتَّة وَ عِشْرُون - ٢٦
سَبْعَة وَ عِشْرُون – ٢٧
ثَمَانِيَة وَ عِشْرُون – ٢٨
تِسْعَة وَ عِشْرُون – ٢٩
I am a technically inclined person. How come I seem to like Arabic numbers? :)
